Lake Sammamish Half
The Lake Sammamish Half is a USATF certified road half marathon held in Redmond, WA, with an in-person and a virtual option. The in-person course follows a paved interurban trail from Marymoor Park in Redmond to Lake Sammamish State Park in Issaquah and has about 70 feet of elevation gain.
Aid stations are placed every 2–3 miles and are stocked with GU gels and Tailwind Endurance Fuel. The event provides pacers for a range of target finish times (1:20, 1:30, 1:40, 1:50, 2:00, 2:15 and 2:30). Because the pathway is narrow for the first mile, the start uses wave starts roughly 90 seconds apart. The course time limit is 4.5 hours.
Participants receive a bib, a commemorative shirt, a finisher medal, free photo downloads and post-race food. All races are cupless; runners should bring a handheld or use a small reusable folding cup available at the start. Free shuttles run from the finish back to the start, and a pre-race shuttle from Lake Sammamish State Park to the start is available with limited space and pre-registration.
Awards for overall top finishers are given to the top three men, women and non-binary runners by gun time; age group awards are in five-year increments and must be picked up on race day. The event is presented by REI. Visit the organization's website for the most recent information.
